The Makefile.dist for GDB version 3.5 contains the line

	TARGET_ARCH=

This doesn't work under SunOS 4.1.   The target option is now `-target sun4',
not `-sun4', and the default rule for compiling is now roughly

	COMPILE.c=$(CC) $(CFLAGS) $(CPPFLAGS) -target $(TARGET_ARCH:-%=%) -c
	.c.o:
		$(COMPILE.c) $<

When you try to compile GDB 3.5 with this new rule, it generates a command
of the form

	cc ... -target -c ...

which isn't valid.  The simplest fix to this problem is to change the
Makefile.dist line

	TARGET_ARCH=

to

	COMPILE.c = $(CC) $(CFLAGS) $(CPPFLAGS) -c

which should work for both SunOS 4.0.3 and SunOS 4.1.
